GeneralGeneralGeneralGeneral The Toshiba TLP2955F consists of a GaAAs light-emitting diode coupled with a high-gain, high-speed photo detector. It is housed in the DIP8 package. The detector has a totem-pole output stage with current sourcing and sinking capabilities. The TLP2955F has an internal Faraday shield that provides a guaranteed common-mode transient immunity of 20 kV/s. The TLP2955F has an buffer output. A inverter output version, the TLP2958F, is also available. The TLP2955F satisfies 8 mm PC board spacing requirements. Absolute maximum ratings and electrical characteristics are the same as in the TLP2955. 3. 3. FeaturesFeatures 3. 3.
